Steps to Completing your Granny Flat Kit


Choose your Design.

View any of our Studio1 Bedroom, 2 Bedroom or 3 Bedroom granny flat designs & choose one that suits your requirements.

Window, Door & Internal Room positions can be changed for no extra charge.


Contact a Private Certifier.

You will need to find & engage a private certifier local to where you are building as they will need to conduct the required inspections as part of your approval.


Get a Quote.

Get in touch with us for a quote including the changes that you have made (window, door & internal wall position changes are free of charge), delivery, engineering certificate & any other requirements that you have.


Pay a Deposit.

When you are ready to start your application process, contact us to pay your initial 10% deposit. Once this has been received, we supply your floor plan, elevations & chassis layout (if purchasing with a gal floor system) including any changes that you have made for your council application.


Soil Test & Foundation Engineering.

You will need to find & engage a soil testing company & structural engineer (usually, your chosen engineer will also do soil testing) local to where you are building. Once your soil test has been completed & soil type determined, your engineer will need to provide a footing or slab design to suit.


Preliminary Approval.

Submit the documentation that you have received so far (floor plan, soil test etc) to your chosen private certifier for preliminary approval subject to building engineering.


Progress Payment.

Once you have received your preliminary approval, you will need to obtain building approval from your certifier. At this stage, we will require a 10% payment (of the total purchase amount) to process your engineering.

Once this payment has been received, the wind rating will be determined for your property. In the event that you require a higher wind rating, we will notify you of wind rating required and the cost involved. Generally speaking, to increase the wind rating to N3 for a 60m² building is an additional $1,800. This includes the upgrade on the windows & doors, roof strapping & framing engineering to N3.

Once the wind rating has been determined, your engineering drawings & engineering certificate will be sent over to you to submit to your certifier.



When you are ready to book your delivery, we will require a 40% booking payment.

A delivery date can be confirmed at this point. Delivery within 2 hours of Yatala is $900.



When your delivery date has been confirmed, we will send through an email to confirm your colour choices for your corrugated iron wall cladding, roofing, gutters, fascia & window & doors frames.

The colour charts for these items can be found below.


Balance Due.

The balance payment for your granny flat is due 2 weeks prior to your delivery.


Delivery Day.

Congratulations! Now the fun begins!

Your items will be delivered in 3 or 4 separate deliveries (3 deliveries for a slab construction, 4 deliveries with a floor system). You will receive the following:

  1. Framing, Chassis (if purchasing with floor system) . For this delivery, we will require at least one extra person onsite to assist with unloading. We do not have a crane truck.
  2. Flooring & HARDIEplank (flooring if purchasing on a chassis & HARDIEplank if this is your chosen external cladding).
  3. CGI Roof Sheets, Wall Sheets, Gutter & Fascia.
  4. Sliding Windows & Sliding Doors.

Please note: Pick up of our kits is not available.
